Researchers have identified 36 common secrets, and they range from infidelity to job dissatisfaction, from romantic desires to criminal behavior, and from having had a traumatic experience to pursuing an unusual hobby.
At any given time, the average person keeps about 12 of them. And while we would like to take some of the big ones to the grave, that's not always possible.

I received a phone call from my late husband’s girlfriend the day of his funeral. She was phoning his cell phone which I had turned off while he was in the hospital. She told me that my husband had been paying her rent for the last year. The bank had recently foreclosed on our house. I had no idea he was unfaithful to me but she knew all about me.
Woman in my town, after she died, people were clearing her garden and found what they thought was a model skeleton Yeah her husband went mysteriously missing in the mid 90s...
My BIL died in an accident, and his wife found out by going through his phone that he was sleeping with several other women. Many of whom were pretty close in our "friend group" and some were also married. It was quite awkward and got pretty messy.
After my father died a few years ago, we learned that he had taken out about 40k of loans on my name. We share the same Initials (and surname obviously). He forged my signature, and kept on applying for loans and credit, got approved and never paid a single dime back. Seeing as he was the main contact, no-one ever called me to ask me why I wasn't paying my debt ... So only after he died we got contacted by institutions informing us that my father owes them money, just to find out it was actually on my name ... So now my credit record is f****d due to years of payments not being made and I need to pay back all of these loans. Fun times right
My grandpa had stashed what would be worth millions today and proceeded to convince his family they were poor and had almost no money. His family lived in poverty while he lied to them all.
I had a brother who had some paranoid delusions (FBI, CIA following him, spying on his apartment, etc). We (my brothers and I) had tried to get him help and he would just have no part of it. After a few years, it seemed like it had gotten better. He stopped bringing it up and we felt like it must have just passed. After he died, we found his journal and it was just horrifying. Right up until the night he died, he detailed all of the torture that they were inflicting on him - weird s**t that I can't even write in here. It was just incredibly disturbing to read what a tortured life he was living inside his mind while acting relatively normal outside. Edit: Many people have asked me to go into more detail on what he wrote. I can't go into much detail - it's hard for me to write about. Briefly, he believed that they were using some type of focused energy beam to torture him. They focused on different parts of his body at different times. Every noise that an appliance made was proof of electronic surveillance. Every bump on the wall or person walking in an adjacent apartment was a message from either the "bad" FBI agents or the "good" FBI agents.
That for the first few months my mother was pregnant with me the entire family thought she was dying from an ovarian tumor. She was 41 and it was the 1960s, her doctor at the navy hospital just assumed she was too old to get pregnant.
My grandparents were horrible to my mom. Telling her she deserved other kids hitting her or not believing her when it happened, telling her "Good, I'm sick of you anyway" when she threatened to run away, physical abuse, spending as little money as possible on her, NEVER showing any kind of affection, etc... I never knew them that well and I'm kinda glad for it [to be honest].
She had been cheating on me all through our marriage. When the shock subsided, it was replaced by rage and betrayal. I lost it and I just started destroying and trashing everything of hers. The only thing I didn't destroy or throw away was her urn. I gave that to her parents. I seriously thought about flushing her ashes down the toilet, but I decided not to. I completely got over her in record time.
one of my good friends was shot last year, he was one of the nicest guys i knew, he always calls everyone he knew checked up on them made sure everyone was okay and was really supportive of everyone. move forward a week or two after his [end] someone was arrested due to a [end] that happened a few days before my friends. turns out the guy who was arrested was the cause of multiple murders (yet he had perfect alibi’s everything) except we later found out that my friend was working for him, was getting paid 5-10k per person. when my friend got murdered it wasn’t a random shooting. it was a revenge hit. no one saw it coming but everything soon made sense
That my grandfather beat my grandmother, to the point of causing miscarriages, and that he also beat my older uncles. Of course, I was only 6 when he died (lung cancer), so it makes sense I never would have heard that stuff before now.
When my great grand mother died my grandma introduce her half sister to the family. Apparently my great grandpa had an affair... the funny thing is at that she went to school with my grandma. No one wanted to tell my great grandma though.
Well I was told by my grandma that on her father's deathbed they found out he had a secret family with another wife and kids and they found out because both family's were at the hospital. He was living a double life pretty much, he sounded like a s****y person.
That my aunt that was stealing from my grandmother. The aunt was withdrawing money of of my grandmother's bank account even after she died. The aunt said my grandmother had a gambling problem but there was no way my grandmother could leave her house by herself. (that was why my aunt had access to her bank account). Means i dont have to see my aunt again which i am happy about.
Apparently my grandfather's sister is actually his sisters daughter AND apparently their dad was the father. I really hope the 2nd part isn't true. I think my pa died having no idea what his father had allegedly done
When my father died, I was sitting around at the wake, just kind of thinking to myself out loud. I told my mother, "It [is bad] that I never got a chance to meet the other Vampedvixen." My mother was like "What are you talking about?" So I told her that our father, her husband for the past several decades, named all three of his daughters after three of his ex-girlfriends. All I know about the other Vampedvixen is she had red hair. My sister confirmed this and said she knew about it too. My mother just sat there dumbfounded, but she found it amusing in the end and was not hurt by it at all. It was just my father's way of being kind to past friends.
My great-uncle was gay. When he died, my mom and aunt were going through his things. My aunt picked up this porcelain egg that opened up. She was confused by it's contents. When she asked my mom what it was, she told her it was pubic hair. My aunt threw it down and ran out of the room screaming. The man collected 3 different colored [private parts] and kept it by his bedside.
Found out my grandfather was wearing a toupee for most of my (and his) life that I had known him. Only found out about it when we were going through old photos and my dad remarked about it. Never saw him the same in photos again.
